Dr. Rodney McKay (Ph.D., Ph.D.), Canadian astrophysicist and engineer of genius intelligence, is the head of science operations of Atlantis. He is also one of the members of Atlantis's first-contact team.

Short Canon Background

McKay is egotistical and brash. Early slurs on his bravery have been belied by his actions over and over again, but unlike the other, more stereotypically macho members of the expedition, McKay is honest and vocal about his fears and irritation in the face of danger and discomfort. Despite his fearfulness, he has shown himself to be courageous, willing to do what must be done despite his fear in the face of things like exploding super volcanoes, Superwraith, and a sinking Atlantis. McKay lacks a brain to mouth filter, which can cause problems for himself and others. Despite his self-proclaimed failings ("petty, arrogant and bad with people"[1]), McKay has earned the loyalty of not only his team members but many others on Atlantis, in part due to his loyalty, bravery, and willingness to put himself in danger to save Atlantis.

Rod McKay and Other Canon AU McKays

We see several canon alternate universe versions of Rodney McKay:

Rodney died, along with everyone else on the Expedition, in S1 episode Before I Sleep. Rodney stayed behind in an attempt to free some of his trapped colleagues, and was last seen in a quickly flooded gateroom.

There is an AU Rodney in the SG-1 episode Moebius who is the lead astrophysicist at a Carterless Cheyenne Mountain; this Rodney is not allergic to lemon, but seems to be largely the same guy (like our-universe Rodney, he also wants to name the puddlejumper a "Gateship.")

We meet a successful, glasses-wearing, dot-com industrialist Rodney McKay in SG-1 episode The Road Not Taken: this McKay is divorced from Samantha Carter.

SGA S4 episode The Last Man has an alternate timeline Rodney who was in a relationship with Jennifer Keller (considered to be married and widowed by some fans, though there is no canon support for this), and then devotes the rest of his life to changing the timeline to restore John Sheppard to the Atlantis Expedition.

SGA S5 episode The Daedalus Variations has reference to at least two Rodneys, the one who built an Alternate Reality Drive and the one who died on the Daedalus with the rest of his team.

Two versions are most popular in fic:

Many stories have been written featuring the smugly popular "Rod" McKay from the Mensaverse (S3 episode McKay and Mrs. Miller): Rod plays golf and is something of an action-hero and a sportsman, and also has a much better relationship with his sister Jeannie than our-universe McKay.

Other fics explore the Dr. McKay in the Vegasverse (S5 episode Vegas), who is part of the SGC and on a team without John Sheppard, though further details are unclear.

Despite, or because of Rodney's personality, many fans have accused Rodney of being the SGA screenwriters' Marty Stu self-insert character. Writer and producer Martin Gero has stated outright that McKay is his favorite character,[2] and the writers often appear to "play favorites" when writing him, perhaps because they see themselves in certain aspects of Rodney.

Canon or Fanon?

Rodney's T-shirt collection is something that fans have grabbed onto and run with. In canon, Rodney is shown wearing an "I'm with Genius" T-shirt during the alien-induced hallucination of returning to Earth in the episode Home, and he wears a "Mr. Fantastic" T-shirt in the SG-1 episode Moebius. Fans have elaborated on these hints, with many stories portraying Rodney (or John) as having a large collection of sarcastic, geek-related, and/or fandom-related T-shirts.[3]

While Rodney states in several episodes that he is allergic to citrus (beginning with his aversion to lemon chicken in SG-1 episode 48 Hours), the extent of the allergy is never shown on screen.[4] Nevertheless, multiple fanfics use anaphylactic shock as a whump mechanism.[5] Rodney also insists he is hypoglycemic,[6] another detail that becomes the subject of many fics.[7]

Minions. Does this term occur in canon or only in fanon?

Fan Response

Fan response to McKay has been mixed. He is featured in various fan works as a layered character with obvious interest in his motivations and personality. Positive views tend to cast him in the light of a misunderstood man with hidden depths, while others see him negatively as nothing more than an arrogant genius.

McKay in Fanfiction

In fanfiction, as in canon, Rodney McKay tends to be voluble, brash, and brave.

McKay's Musical Career

The Stargate SG-1 episode 48 Hours provides a piece of backstory about McKay's childhood ambition to be a concert pianist; his teacher told him that, although technically proficient, he lacked the artistry and soul to be truly great. Many stories use this detail:

McKay's Mental Health

Canon makes much of McKay's intelligence. He's a genius (and he knows it), and he talks fast because he has a lot to say. Fanfiction sometimes subverts these basic realities.

There are also stories in which McKay is unhinged, unwell, or mentally ill; Korilian maintains The Deranged Mckay Master List, a collection of links to stories where McKay is deranged, broken, or otherwise messed-up.

Enhanced/Subtracted Senses

In the wake of Season Three's The Tao of Rodney, a wash of stories enhanced McKay's senses and abilities (The Fey by Oran). Fanwriters have also explored what happens if McKay's senses are taken away (The Paradox of Vision by Apple_Pi).

AU McKays are usually irascible and arrogant, but tempered with moments of kindness.

Genderswap

Some fans have argued that canonical McKay is effectively occupying a stereotypically female role anyway: he's the scientist/intellectual on a team of warriors (which Others him in interesting ways), and there's John's infamous reference to Rodney's comfort eating[8] Not to mention that his true given name is Meredith.

Some other fans see Rodney as having several stereotypically masculine traits (for example his passion for hard science, a historically male-dominated field, and his awkwardness dealing with emotions, a skill someone gendered female would be expected to develop), and may be interested in genderswap to explore how Rodney deals with people's reactions to the way those traits directly defy gender role expectations for women. Sometimes Rodney is seen as transgender; as having been born a female Meredith but having become a male Rodney instead (see, for instance, Life (Sometimes It Washes Over Me) by kyuuketsukirui.)

Of course, Rodney has also canonically genderfucked: he was forced to share his body with Lt. Laura Cadman in the episode Duet.

Rodney Transformed

Rodney has been transformed into a penguin (many stories), a dolphin, a baby dinosaur, a dragon, an ice cube, a girl scout cookie (specifically, a Samoa), a cat, a squirrel, etc. He has been portrayed as an alien being (An Aesthetic Solitary Thing by eliade). Fans made Rodney into a hologram well before canon did in episode The Last Man.

McKay Whumping

The Post-Trinity phenomenon: Love it or hate it, iibnf has been maintaining a list of post-Trinity fic for those who can't get enough of Rodney being shunned and kicked around:

Normally, in a classic Post-Trinity fic, John Sheppard (sometimes the entirety of Atlantis) cannot forgive Rodney for making a mistake, and proceeds to punish him, usually by shunning. A lot of shunning. Oftimes Rodney may also be served lemon chicken in the mess, his work may be sabotaged, people will be mean to him, generally his life is made more unpleasant. Poor woobie.[9]

Most of the classic post-trinity stories focus on the other characters - with a special focus for John - learning how difficult their life would be without Rodney in it.
